Abstract

For stationary wireless ad hoc networks, one of the key challenging issues in routing and multicasting isto conserve as much energy as possible without compromising path efficiency measured as end-to-enddelay. In this paper, we address the problem of path efficient and energy aware multicasting in staticwireless ad hoc networks. We propose a novel distributed scalable algorithm for finding a virtualmulticast backbone (VMB). Based on this VMB, we have further developed a multicasting scheme thatjointly improves path efficiency and energy conservation. By exploiting inherent broadcast advantage ofwireless communication and employing a more realistic energy consumption model for wirelesscommunication which not only depends on radio propagation losses but also on energy losses intransceiver circuitry, our simulation results show that the proposed VMB-based multicasting schemeoutperforms existing prominent tree based energy conserving, path efficient multicasting schemes.
